Definitions
- the present invention relates to an ultraphobic surface, processes for its production and its use.
- the surface has a surface topography in which the spatial frequencies f of the individual Fourier components and their amplitudes a (f) are expressed by the integral of the function S
- Ultraphobic surfaces are characterized by the fact that the contact angle of a drop of a liquid, usually water, lying on the surface is significantly more than 90 ° and that the roll angle does not exceed 10 °. Ultraphobic surfaces with a contact angle> 150 ° and the above Roll-off angles have a very high technical benefit because they e.g. with water but also with
- Self-cleaning is understood here to mean the ability of the surface to easily release dirt or dust particles adhering to the surface to liquids that flow over the surface.
- EP 476 510 AI discloses a method for producing an ultraphobic surface, in which a metal oxide film is applied to a glass surface and then etched using an Ar plasma.
- the surfaces produced with this method have the disadvantage that the
- US Pat. No. 5,693,236 also teaches a number of processes for the production of ultraphobic surfaces, in which zinc oxide brings microneedles onto a surface with a binder. and are then partially exposed in different ways (e.g. by plasma treatment). The surface structured in this way is then coated with a water-repellent agent. Surfaces structured in this way, however, also only have contact angles of up to 150 °.
- the roll angle here is understood to be the angle of inclination of a fundamentally planar but structured surface against the horizontal, at which a standing water drop of volume 10 ⁇ l is moved due to gravity when the surface is inclined.
- a particular problem is that the ultraphobic property is evident on surfaces of the most varied of materials with a completely different surface structure, as can be seen from the examples mentioned above. So far, there is no method that is able to determine the ultraphobic property of a surface regardless of the material. Another object of the invention is therefore to find a method with which surfaces can be checked for the ultraphobic property, regardless of the material.
- the object is achieved according to the invention by a structured surface with ultra-phobic properties, which is characterized in that it has a
- a hydrophobic material in the sense of the invention is a material which shows a contact angle with respect to water of greater than 90 ° on a flat, non-structured surface.

- the surface topography of an ultraphobic surface under a drop of liquid has elevations and depressions, the height or depth of which vary between 0.1 nm and 1 mm. Because of this enormous range, it is not yet possible to determine the surface topography with a single measurement method, so that 3 measurement and evaluation methods have to be combined with one another in order to be able to determine the surface topography precisely. These measurement methods are:
- WLI White light interferometry
- WLI White light interferometry
- ⁇ f 7 x 10 "3 ⁇ m " 1 to 2 x 10 ° ⁇ m "1 is measured.
- a height profile z (x, y) is determined with a white light interferometer, where z is the height above any reference height z 0 at the respective location x or y.
- the exact experimental setup and the measuring method can be found in RJ Recknagel, G. Notni, Optics Commun. 148, 122-128 (1998).
- the height profile z (x, y) is converted in the same way as in the case of the atomic force microscopy or scanning tunnel microscopy described below.
- ⁇ f 1 ⁇ m "1 to 3 x 10 2 ⁇ m " 1 is measured.
- the height profile z m , n is related to any reference height z 0 , m, n are measuring points in the x and y directions, which are recorded at an equidistant distance ⁇ L.
- the height profile data are converted into the averaged spectral power density PSD according to equations 1 and 2 of the publication by C. Ruppe and A. Kurre, Thin Solid Films, 288, (1996), page 9.
- Different scanning ranges L x L are also used in this measuring method. With these scanning areas and the number of data points N, the minimum or maximum spatial frequency can be calculated, which can be examined per scanning area, where:
- 512 measuring points are used per scanning area, so that in
- Scanning range 0.5 ⁇ m x 0.5 ⁇ m a spatial frequency range of:
- Scanning range 0.1 ⁇ m x 0.1 ⁇ m a spatial frequency range of:
- ⁇ f 1 x 10 1 ⁇ m "1 to 3 x 10 3 ⁇ m " 1 is measured.
- the height profile z m> n is related to any reference height z 0 . m, n are

Torre, Thin Solid Films, 288, (1996), page 10-11, Figures 1-4 show the result for PSD (f) curves in double logarithmic representation, plotted as log (PSD (f) / nm 4 ) as a function of log (f / ⁇ m "1 ).

- Roughening of a surface due to spherical particles of a uniform size is unfavorable.
- the additional roughening of the particle surfaces by means of smaller structures for example small particles which sit on or adhere to the large ones but are not present separately from the large particles, is favorable.
- the depressions in a scratch mark must in turn be as rough as possible within the next dimension. If this is not the case, the primary depressions in turn have to be roughened in a further work step.
- the new knowledge described here does not limit the shape or profile of the depressions or rough structures.
